Objective: To investigate the efficacy of ultrasound-guided transabdominal follicular aspiration when the ovaries are not accessible transvaginally.
Design: Retrospective case-control study.
Setting: University-hospital based in vitro fertilization (IVF) clinic.
Patient(s): 69 women undergoing transabdominal follicular aspiration for oocyte retrieval, including 12 cases of mixed abdominal/vaginal aspiration, compared with controls matched by age, follicle number, and year of procedure undergoing standard transvaginal aspiration.
Intervention(s): Transabdominal follicular aspiration when one or more ovaries could not be retrieved via standard transvaginal aspiration.
Main Outcome Measure(s): Total and mature oocytes retrieved, damaged oocytes, fertilization rate, embryo number and quality, and clinical and ongoing pregnancy rates.
Result(s): Cases of transabdominal aspiration had slightly fewer oocytes retrieved, but no statistically significant differences were found for damaged oocytes, fertilization rates, embryo number and quality, or pregnancy rates. In 12 years, one complication requiring hospitalization was noted.
Conclusion(s): This study demonstrates that transabdominal ultrasound-guided follicular aspiration is safe and efficacious, yielding clinical results in women with significant ovarian displacement, comparable with results achieved by transvaginal aspiration in women with normally positioned ovaries. Transabdominal ultrasound-guided aspiration should be the modality of choice when the ovaries are not accessible transvaginally.

Objective: To evaluate the feasibility, safety, and efficacy of microwave ablation (MWA) for the treatment of patients with Bethesda IV follicular neoplasms (FNs) (≤3 cm).
Methods: In the retrospective study, patients who underwent MWA for Bethesda IV follicular neoplasms (≤3 cm) were included. Technical success, volume reduction, disease progression, and adverse event (AE) rates were analyzed postablation.
Challenges in Diagnosing Adolescent Goiter: A Case Report with Brief Literature Insights in Juvenile Desmoid-Type Fibromatosis of the Thyroid Gland.

The prevalence of goiter, thyroid nodules, and thyroid cancers in the pediatric population has increased. In some rare cases, local conditions such as juvenile desmoid-type fibromatosis (JDTF) can mimic specific thyroid pathology, complicating the diagnostic process. A 17-year-old obese adolescent girl was admitted to the Endocrinology Department with progressive swelling on the left side of the neck, persisting for approximately one year, recently accompanied by dysphonia and inspiratory dyspnea, and ultimately diagnosed as a unilateral nodular goiter associated with compressive phenomena.

Background: The differential diagnosis between benign and malignant thyroid nodules continues to be a major challenge in clinical practice. The rising incidence of thyroid neoplasm and the low incidence of aggressive thyroid carcinoma, urges the exploration of strategies to improve the diagnostic accuracy in a pre-surgical phase, particularly for indeterminate nodules, and to prevent unnecessary surgeries. Only in 2022, the 5th WHO Classification of Endocrine and Neuroendocrine Tumors, and in 2023, the 3rd Bethesda System for Reporting Thyroid Cytopathology and the European Thyroid Association included biomarkers in their guidelines.

Cystic ovarian disease (COD) is a major cause of infertility in dairy cows. This study aimed to investigate the impact of follicular cysts on the invitro blastocyst developmental competence of oocytes and the relative gene expression of blastocysts developed from the subordinate follicles of ipsilateral (ovary with cyst), contralateral (ovary opposite to cyst), and normal ovaries of buffaloes. A total of 2059 ovaries were collected from slaughterhouse and classified into three categories based on the presence of follicular cysts: a) ipsilateral, b) contralateral, and c) control (absence of cysts).

Granulosa cells (GCs) are pivotal in the development of ovarian follicles, serving not only as supportive cells but also as the primary producers of steroid hormones. The proliferation of these cells and the synthesis of steroid hormones are crucial for follicular development and atresia. In our study, GCs were isolated using follicular fluid aspiration and subsequently identified through immunofluorescence.
